I had horrible arthritis in various parts of my body, especially the knees, wrists, neck and ankles. It came on last fall after being in a flare all summer that was out of control. At times I could hardly move it was so bad. I have now been in remission for several months now and seem to get stronger with time. I have noticed that as I have gotten better with the UC the arthritis seems to have for the most part gone away although there was some lag time so it was hard to correlate the IBD symptoms with the arthritis. I thought I would have it forever as it was really bad through the winter and up through this spring but it has gone away with the UC symptoms. I'm hoping this lasts for a good while! What I found out when I had it is that as others have said it is a potential symptom that comes along with UC. It seems the inflammation in the gut sparks inflammation in other areas of the body.
